Water Chiller Repair

Methodical fault finding for chilled-water systems, from the refrigeration circuit to pumps, controls and heat transfer.

The equipment

How the system does its job.

A water chiller removes heat from a circulating water or water-glycol loop, then distributes that cooling through air handlers, fan-coil units or process equipment. Because performance depends on refrigerant, water flow, controls and heat rejection working together, a useful diagnosis looks at the complete system rather than one component in isolation.

Diagnosis before decisions

Read the warning signs. Test the cause.

Common faults and warning signs

High leaving-water temperature
Unexpected trips or alarm codes
Low water flow or unstable pressure
Noise, vibration or rising energy use

What we inspect or repair

Operating pressures and temperatures
Compressor, contactor and electrical checks
Evaporator and condenser condition
Pump flow, valves, strainers and sensors
Controls, safeties and set-point operation

A clear service process

From symptom to stable operation.

Measurements guide the repair scope. After the agreed work, operation is checked again against the original symptom.

01
Review
Confirm the load, recent alarms and operating history.
02
Measure
Check water temperatures, flow, refrigerant readings and electrical values.
03
Repair
Address the agreed mechanical, electrical or control fault.
04
Verify
Run the chiller under load and confirm stable leaving-water performance.

Preventive maintenance guidance

Keep condenser surfaces and strainers clean.
Record approach temperatures, pressures and alarm history.
Check water treatment, pump condition and sensor calibration on a planned schedule.
